A to Z: Marvels in Paper Engineering is a juried collection of individual pop-up spreads, each focusing on a letter of the alphabet. The goal is to showcase and celebrate some of the best Paper Engineers around the world as they translate their unique styles into each letter to highlight and celebrate the 25th Anniversary of The Movable Book Society with a commemorative book that would be released in August 2018.

The Movable Book Society (MBS) is an international organization that was established in 1993 to provide a forum for collectors, artists, curators, book sellers, book producers, and others to share enthusiasm and exchange information about pop-up and movable books. The Society has about 400 members worldwide.

Previous collaborative projects include: Brooklyn Pops-Up (2000) and A Celebration of Pop-up and Movable Books: Commemorating the 10th Anniversary of the Movable Book Society (2004).
